Surveyors can take measurements as soon as the theodolite is turned on with the built-in absolute encoder. This technology uses advanced algorithm to restore the azimuth after the instrument’s power is cut off, improving reliability of angle measurements and reducing power consumption.

Fast Set-Up

The DT209 also includes a fixed tribrach with bubble vial and a built-in optical plummet for precise positioning and leveling of the instrument on the jobsite.

Single Display and Functional Keys

A large LCD display and simple five-button panel provide you with a simple interface to quickly take horizontal and vertical angle measurements.

Ultimate in Continuous Operation

With an IP-66 rating for dust and water protection, the DT 209 digital theodolite promotes productive surveying even in harsh weather. Its telescope is also constructed to prevent moisture and eliminate lens fogging. Compact and lightweight, this survey tool offers up to 170 hours of continuous measurement in angle mode using four standard AA alkaline batteries.
